This document introduces Panasonic's audio analyzer series, including VP-7728A, VP-7723B, and VP-7726A. These audio analyzers feature high performance, versatility, and multi-channel capabilities, making them ideal for evaluating and measuring digital audio devices such as CD, MD, and DVD. They are equipped with a pre-low pass filter (Pre-L PF) and basic measurement functions such as AC level measurement, DC level measurement, harmonic distortion measurement, frequency measurement, and Wow & Flutter measurement. In addition, they have a wide range of measurement filters and additional features, such as preset memory, limit determination, auto sequence, GP-IB, and remote interface.
The Panasonic audio analyzer series (VP-7728A, VP-7726A, VP-7723B) offers five basic measurement functions such as AC level, DC level, THD+N, frequency and optional wow‑flutter. It supports a wide frequency range, high‑output signal source, and multiple channels for comprehensive digital audio evaluation.
The units include extensive interfaces (GP‑IB, remote control, 8‑channel multiplexed input), memory functions with up to 100 points, optional filters, and detailed specifications for signal levels, output, and environmental limits. This manual is written in Japanese.
